Simrad 9420024128749, Product Brief

Page: 24 / 98

The radar transmits a powerful, but very short pulse, at fixed frequency.
The pulse propagates outwards in a direction determined by the angle of the rotating radar
antenna at the time of transmission.
The radar then switches to receive mode to listen for reflections.
If the pulse reflects off an object, it will return to the receiver with a delay proportional to the
distance of the object from the transmitter.
The antenna angle at the time of pulse transmission equals the direction of the object.
